The composition possesses at least one good property chosen from staying power, gloss, and comfort.

[0001] The present application claims benefit of U.S. ProvisionalApplication No. 60/410,955, filed Sep. 17, 2002.

[0002] The present disclosure relates to a cosmetic compositioncomprising, in a physiologically acceptable medium, at least onehigh-viscosity phenylsilicone oil, at least one non-volatile hydrocarbonoil, at least one rheological agent, and at least one particulate phase.This composition may be in the form of a care or makeup composition forthe skin, both of the human face and of the human body, including thescalp, lips or exoskeletal appendages of human beings, such as the hair,eyelashes, eyebrows or nails. The composition as disclosed hereinpossesses notable cosmetic properties, such as staying power, and givesthe makeup or care product properties of gloss and/or comfort.

[0003] The composition as presently disclosed may be in the form of amakeup product for keratin materials (e.g., skin, lips, and exoskeletalappendages), possibly having non-therapeutic treatment and/or careproperties. For example, the composition may be in the form of alipstick, lip gloss, foundation, loose or compacted powder, blusher,eyeshadow, makeup base, concealer, tattooing product, mascara, eyeliner,nail varnish, artificial tanning product, and haircare or hair colouringproduct.

[0004] The use of silicone compounds in cosmetic compositions, such asmakeup compositions, is familiar to formulators. Mention may be made,for example, of EP-A-0407205, which describes a composition comprisingthe combination of a silicone gum and a silicone oil that has goodstaying power, spread and comfort properties. For instance, thiscombination imparts excellent sensorial properties to cosmeticcompositions, such as a non-greasy feel, spreading properties, andlubricity properties, and can allow a particularly homogeneous film tobe obtained on the skin.

[0005] Also known is the use of silicone compounds for the purpose ofincreasing the staying power of cosmetic compositions, for examplemakeup. The problems of poor staying power are characterized by a changein colour (colour change, fade) generally as a result of interactionwith sebum and/or perspiration secreted by the skin, in the case offoundation and rouge, or of interaction with the saliva in the case oflipsticks. These problems can require the user to apply fresh makeup atfrequent intervals, which may constitute a loss of time.

[0006] However, silicone compounds may sometimes cause formulatingproblems, for instance, difficulties of dispersing pigments into thecompositions comprising silicone media, thereby giving rise to poordevelopment of the hue of the composition and to a granular appearance,which discourages the consumer from using this type of product, andwhich is unfavourable to the production of a glossy composition.

[0007] But there are numerous cosmetic compositions for which the glossproperties of the deposited film, following application to the keratinmaterials (skin, lips, exoskeletal appendages), are very important.Mention may be made, for example, of lipsticks, eyeshadows, nailvarnishes, and certain hair products.

[0008] FR 2 771 628 describes the use of a silicone gum in solution in aphenyltrimethicone oil in a cosmetic composition. This gum has theadvantage of being soluble with the oils commonly used in cosmetics.

[0009] EP 1 112 734 describes a transfer-resistant compositioncomprising a hydrocarbon oil and a silicone oil, which are insoluble inone another. The composition further comprises a volatile solvent.

[0010] In order to enhance the gloss it is known among formulators touse oils having a high viscosity and a high refractive index, such asoily polymers, for instance polybutenes or certain vegetable oils(castor oil for example). However, these compounds do not make itpossible to obtain a film of a composition whose staying power, forexample in terms of the gloss, is sufficient to last throughout the day.

[0011] It has been found, surprisingly, that the use of the combinationof at least one high-viscosity phenylsilicone oil and at least onenon-volatile hydrocarbon oil, which are soluble or dispersible in oneanother, makes it possible to obtain a composition that exhibits goodcosmetic and/or sensorial properties, for example properties of stayingpower over time, and also properties of gloss and comfort. Additionally,such a composition may not irritate keratin materials.

[0012] The present disclosure provides a cosmetic compositioncomprising, in a physiologically acceptable medium, at least onephenylsilicone oil having a viscosity greater than or equal to 500 cStand at least one non-volatile hydrocarbon oil having a molecular mass ofmore than 500 g/mol, wherein the composition has an average gloss ofmore than 100 out of 200 and a post-trial staying power of more than 40out of 100.

[0013] The average gloss is measured with the aid of a gloss meter,conventionally, by the following method. A Leneta contrast chartreferenced Form 1A Penopac is spread with a 50 μm layer of thecomposition whose average gloss is to be evaluated, using an automaticspreader. The layer covers at least the white background of the chart.The gloss is then measured immediately at 20° on the white backgroundusing a Byk Gardner microTri-Gloss gloss meter. The gloss of thecomposition can also be measured one hour after the composition has beenapplied.

[0014] The average gloss of the composition, measured at the time ofapplication, can be, for example, greater than 120, 130, 140, 150 out of200, such as 160 out of 200.

[0015] The average gloss of the composition measured one hour afterapplication can be greater than 120 out of 200, and, for furtherexample, 130 out of 200.

[0016] The post-trial staying power of the composition disclosed hereincan be evaluated as follows on a group of at least 10 persons. Thereduced diffusion index of incident light on the lips on which thecosmetic composition may be applied is measured on every person with afilm camera. The mean of the ten measurements is calculated. Themeasurement conditions are described in patent application FR0207108,which content is incorporated herein by reference. Each person thenapplies his or her lips on a paper tissue. The reduced diffusion indexof incident light on the lips with make-up is measured again, and themean of measures is calculated. The persons involved in evaluating thestaying power drink a hot drink and then a glass of water and eat fourbites of sandwich and half an apple. The reduced diffusion index ofincident light on the lips with make-up, after this meal, is measured.The mean of the measurements is then calculated.

[0017] The post-trial staying power is expressed as a percentage of a)the difference between the reduced diffusion index of the lips withmake-up, after the meal, and the reduced diffusion index of the nakedlips before applying the make-up, and of b) the difference between thereduced diffusion index of the lips with make-up, before the meal, andthe reduced diffusion index of the naked lips.

Polymeric organic lipophilic gellingagents are, for example, partly or totally crosslinked elastomericorganopolysiloxanes, of three-dimensional structure, such as those soldunder the names KSG6, KSG16, and KSG18 by Shin-Etsu, Trefil E-505C orTrefil E-506C by Dow Corning, Gransil SR-CYC, SR DMF10, SR-DC556, SR5CYC gel, SR DMF 10 gel, and SR DC 556 gel by Grant Industries, and SF1204 and JK 113 by General Electric; ethylcellulose, such as those soldunder the name Ethocel by Dow Chemical; copolymers of a C₃₆ diacidcondensed with ethylenediamine, with a weight-average molecular mass ofapproximately 6 000, such as the compounds sold by Arizona Chemicalunder the names Uniclear 80 and Uniclear 100, gums, for instance,silicone gums, such as the PDMS, having a viscosity>100 000 centistokes,galactomannans comprising from one to six, for example from two to four,hydroxyl groups per saccharide unit, substituted by saturated orunsaturated alkyl chain, such as guar gum alkylated with C₁ to C₆, forexample C₁ to C₃ alkyl chains, and mixtures thereof.

[0083] As suitable non-limiting examples of lipophilic gelling agents,mention may be made of non-polymeric, molecular organic gelling agents,also referred to as organogellers, which are compounds whose moleculesare capable of establishing physical interactions between themselvesthat lead to self-aggregation of the molecules, with formation of a 3Dsupramolecular network, which is responsible for gelling the liquidfatty phase.

[0084] A “liquid fatty phase” for the purposes of the present disclosureis a fatty phase which is liquid at ambient temperature (25° C.) andatmospheric pressure (760 mm Hg or 105 Pa), and is composed of one ormore fatty substances which are liquid at ambient temperature, alsocalled oils, which are generally mutually compatible. According to oneaspect of the disclosure, this liquid fatty phase is composed of thenon-volatile hydrocarbon oils described above.

[0085] The supramolecular network may result from the formation of anetwork of fibrils (which are due to stacking or aggregation oforganogeller molecules), which immobilizes the molecules of the liquidfatty phase.

[0086] The aptitude to form this network of fibrils, and hence to gel,depends on the nature (or chemical class) of the organogeller, on thenature of the substituents carried by its molecules for a given chemicalclass, and on the nature of the liquid fatty phase.

[0087] The physical interactions are diverse but excludeco-crystallization. These physical interactions are, for example,interactions of the self-complementary hydrogen interaction type, πinteractions between unsaturated rings, dipolar interactions,coordination bonds with organometallic derivatives, and combinationsthereof. Generally speaking, each molecule of an organogeller is able toestablish a number of types of physical interaction with a neighboringmolecule. Also, the molecules of the organogellers according to thepresent disclosure may suitably include at least one group that iscapable of establishing hydrogen bonds and, for example, at least twogroups which are capable of establishing hydrogen bonds, at least onearomatic ring, for example, at least two aromatic rings, at least one ormore ethylenically unsaturated bonds and/or at least one or moreasymmetric carbons. The groups capable of forming hydrogen bonds aresuitably selected from hydroxyl, carbonyl, amine, carboxylic acid,amide, urea and benzyl groups, and combinations thereof.

[0088] The at least one organogeller according to the present disclosureis soluble in the liquid fatty phase after heating to the point where atransparent, homogeneous liquid phase is obtained. The at least oneorganogeller may be solid or liquid at ambient temperature andatmospheric pressure.

[0089] The at least one molecular organogeller that can be used in thecomposition according to the present disclosure include, for example,those described in “Specialist Surfactants” edited by D.

[0138] The procedure was the same as that of Examples 1 to 4.

[0139] Cosmetic Evaluation

[0140] The staying power of this composition was evaluated usinginstrumental and sensorial methods on a panel of 12 qualified persons,who applied the lipstick.

[0141] The staying power was evaluated as follows:

[0142] in the first phase, an evaluation of the overall “sensorial”staying power is carried out one hour after application of the formulato the lips.

[0143] in the second phase, an “instrumental” staying power wasevaluated after a series of tests, which consist in making two “bites”on a paper tissue, drinking a hot drink and then a cold drink and eating4 bites of a sandwich and of an apple.

[0144] The sensorial staying power was evaluated on a scale from 1 to10:1 corresponds to a formula which has no staying power at all and 10to a formula whose staying power is very good.

[0145] The instrumental staying power was evaluated on a scale from 1 to100:1 corresponds to a formula that has no staying power at all and 100to a formula whose staying power is very good.

[0146] The gloss and comfort were also evaluated by these 12individuals:

[0147] the gloss was evaluated just after the application of the formulaand then after one hour (the instrumental gloss was evaluated on a scaleranging from 1 to 200. 1 corresponds to a formula which is not glossy atall and 200 to a very glossy formula.)

[0148] The instrumental gloss was measured with the aid of a glossmeter, conventionally, by the following method.

[0149] A Leneta contrast chart referenced Form 1A Penopac was spreadwith a 50 μm layer of the composition whose average gloss is to beevaluated, using an automatic spreader. The layer covers at least thewhite background of the chart. Then the gloss was measured at 20° on thewhite background using a Byk-Gardner microTri-Gloss gloss meter.

[0150] the comfort was evaluated after one hour. Results Staying powerGloss Comfort Sensorial evaluation On application 6.3 After 1 hour 6.44.8 7.4 Instrumental evaluation On application 171 After 1 hour 82 138After tests 54
